Propoxur was evaluated by the JMPR in 1973, 1977, 1981, 1983 and 1991. At the 1994 CCPR, several delegations expressed the opinion that the MRLs recommended by the 1991 JMPR for head lettuce and potatoes were based on very old data. The manufacturer stated that new data on potatoes would be available for the 1996 JMPR and that additional studies were scheduled for lettuce. New data from supervised trials on these commodities were provided to the Meeting.
